VirtualBox is a general-purpose full virtualizer for hardware. Targeted at server, desktop and embedded use, it is now the only professional quality virtualization solution that is also Open Source Software. VirtualBox is a powerful virtualization product for enterprise as well as home use. VirtualBox provides are useful for several scenarios: Running multiple operating systems simultaneously. VirtualBox allows you to run more than one operating system at a time. This way, you can run software written for one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot to use it.
Since you can conï¬gure what kinds of "virtual" hardware should be presented to each such operating system, you can install an old operating system such as DOS or OS/2 even if your real computer's hardware is no longer supported by that operating system.
Software vendors can use virtual machines to ship entire software conï¬gurations. For example, installing a complete mail server solution on a real machine can be a tedious task. With VirtualBox, such a complex setup (then often called an "appliance") can be packed into a virtual machine. Installing and running a mail server becomes as easy as importing such an appliance into VirtualBox.
Testing and disaster recovery. Once installed, a virtual machine and its virtual hard disks can be considered a "container" that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts. On top of that, with the use of another VirtualBox feature called "snapshots", one can save a particular state of a virtual machine and revert back to that state, if necessary. This way, one can freely experiment with a computing environment. If something goes wrong (e.g. after installing misbehaving software or infecting the guest with a virus), one can easily switch back to a previous snapshot and avoid the need of frequent backups and restores. Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time. You can delete snapshots while a VM is running to reclaim disk space.
Infrastructure consolidation. Virtualization can signiï¬cantly reduce hardware and electricity costs. Most of the time, computers today only use a fraction of their potential power and run with low average system loads. A lot of hardware resources as well as electricity is thereby wasted. So, instead of running many such physical computers that are only partially used, one can pack many virtual machines onto a few powerful hosts and balance the loads between them.
VirtualBox 5.1.12 (released 2016-12-20)
This is a maintenance release. The following items were fixed and/or added:
VMM: fixed VERR_IEM_ASPECT_NOT_IMPLEMENTED Guru Meditations with certain Linux guests if KVM paravirtualization is enabled (5.1 regression; bugs #15613 and #16251)
VMM: fixed VERR_VMX_UNABLE_TO_START_VM Guru Meditations under rare conditions
GUI: prevent a crash under certain conditions if the VM is terminated very early
GUI: fixed certain keyboard capture issues (5.1.10 regression; Mac OS X hosts only; bug #16150)
GUI: fixed dragging guest windows in seamless mode with the keyboard captured (X11 hosts only; bug #15837)
GUI: fixed a problem where the new version detected dialog was covered by the appliance import dialog (Mac OS X hosts only; bug #16238)
Storage: fixed NVMe reset processing when doing rmmod nvme; modprobe nvme in a Linux guest (bug #16080)
Storage: fixed creating a snapshot when the VM is running and an NVMe controller is present
Storage: fixed a problem with the LsiLogic SCSI controller where requests could be lost with SMP guests
E1000: fixed "cable disconnected" issue (Mac OS X guests only; 5.1.10 regression; bug #16260)
E1000: fixed "TX unit hang" issue (Linux guests only; 5.1.10 regression; bug #16221)
Parallel ports: fixed port enumeration on Windows host (bugs #15872 and #16127)
API: don't crash when sanitizing certain VM names (bug #16299)
Linux hosts: automatically disable asynchronous I/O on Linux 2.6.18 kernels as high I/O load may trigger kernel oopses on these kernels if this feature is enabled
Linux hosts / guests: Linux 2.6.28 compile fix (bug #16267)
Linux hosts: compile Linux 4.9 compile fix (bug #16286)
Linux Additions: warn the user about a known bug with older Linux guests (e.g. Debian 7) requiring manual work to get 3D working (bug #15319)
Linux Additions: fix the graphics driver build with Linux 4.10 and later (bug #16298)
Windows Additions: fixed a crash in the WDDM driver under certain conditions
